Commit fc551d7 introduced the wrappers abd_enter_critical() and
abd_exit_critical() to mark critical sections. On Linux these are
implemented with the local_irq_save() and local_irq_restore() macros
which set the 'flags' argument when saving. By wrapping them with
a function the local variable is no longer set by the macro and is
no longer properly restored.
Convert abd_enter_critical() and abd_exit_critical() to macros to
resolve this issue and ensure the flags are properly restored.
